Patent Searching and Data


Title:
MANAGEMENT DEVICE, POWER STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/176395
Kind Code:
A1
Abstract:
The present invention provides a management device and a power storage system. A voltage detection unit (12) detects the voltages of each of a plurality of cells (E1-Em) connected in series. A plurality of discharge circuits (11) are respectively connected in parallel to the plurality of cells (E1-Em). A control unit (15) controls the discharge time of the plurality of discharge circuits (11) based on the voltages of the plurality of cells (E1-Em) that are detected by the voltage detection unit (12), and thereby performs control so that voltage/capacity of the plurality of cells (E1-Em) may conform to a target value. The control unit (15) sets the target value higher as the amount of change in voltage of the plurality of cells (E1-Em) in a prescribed period becomes larger.
